A New Standard of Line-Following Performance

The highlight of this generation is the brand-new 10-channel Line Tracer, giving MATRIX robots the fine-tuned responsiveness that mission-based competitions demand. It doesn’t simply “follow a black line.” It reads deviations at high resolution, corrects direction smoothly, and handles curves with confidence. 

With MA321 Matrix R4 MissionGo Set, mission runs no longer depend on luck — they depend on skill. 

Overview

The Line Tracer 10 CH is a high-precision line-tracking sensor module equipped with 10 sets of sensing channels. It transmits ground detection data to the controller via I²C communication. It can accurately determine the line's Error (offset from the center) and Line Width, and features junction recognition to automatically identify complex terrains such as Left turns, Right turns, T-junctions, or Cross-junctions. This module features low power consumption and operates stably even in low-light environments.

Feature

• 10-Channel Sensor Array: Provides more detailed linetracking capabilities compared to traditional sensors.

• Automatic Junction Identification: Built-in algorithms automatically determine Left, Right, T, or Cross-junction types.

• Line Width Calculation: Measures line width and records the last sensor position before a line was lost.

• Low Power & Low Light Optimization: Designed for energy efficiency and reliable detection in weak lighting.

• Intuitive Calibration: Features a built-in CAL button and blue indicator light for easy on-site calibration without complex programming.

• Wide Voltage Support: Supports 3.3V ~ 5V operating voltage for easy integration.

Application

• Precision Line-Following Robots: Utilizing high-resolution 10-channel offset data for smooth PID steering control.

• Smart Intersection Navigation: Identifying junction types via Junction Type data for precise turning in mazes.

• Competition Logistics Robots: Using the Last Sensor record to quickly recover paths if a line is momentarily lost.

• Ground Feature Analysis: Real-time monitoring of line width changes and ground optical reflection for data analysis.
